PFAS, which stands for perfluoroalkyl substances, is in a class of toxic chemicals including PFA, PFOA, PFOS, C8, and closely related to PFC (perfluorochemicals) and C6. They are manmade, highly persistent substances in the environment and human body, and one of the most potent and longest-lasting greenhouse gases emitted by human activity, according to the EPA. PFCs were introduced to the environment after World War II and are now present in the blood of most people worldwide. They have been used to make carpets, clothing, fabrics, paper packaging for food, cookware, and other materials that are resistant to water, grease, or stains. PFOS and PFOA is suspected to increase cholesterol, affect the immune system, and increase cancer risk.

The continued use of this class of chemicals is unacceptable and to overcome this problem, we encourage public awareness and alternative water repellents. For additional information, see the articles and resources here.
